New Stepper Driver!

[Fish4Fun]

Dynomotion has introduced a new stepper driver, the KStep ( http://www.cnczone.com/forums/dynomo...s_stepper.html ). I was able to purchase one a few weeks ago (before they were officially released), and have had a chance to test it. It is designed specifically to interface with their KFlop interface, but is perfectly capable of operation from the LPT port with Mach3/EMC2 (it will require converting the DB25 to a 24 pin dual row header, but that is not a particularly difficult task). It has 16 microsteps per step, so using Mach3/EMC2 with the LPT port will require a fairly high frequency pulse train (48,000 steps per second for 900RPM in a 200 step/revolution stepper) if you are using single start ACME lead screws, you should make sure your PC/OS can handle the fast pulse train.

I thought I would mention this driver here in the DIY section because the KStep is a 4 Axis driver that offers up to 5A per axis and has a retail price of only $199 and that makes it very attractive to DIYers looking for a great value in a driver.

I currently have a G540 in my desktop CNC; I plan to put the KStep in my new build (hopefully I will start on that soon, lol. I have rails/trucks, steppers and a driver, so all I need now is time!) I have tested the KStep with both NEMA23's and a NEMA34, and it performs beautifully. I would be happy to answer any user-oriented questions about the KStep, please direct any technical questions to Tom in the Dynomotion forum.

Doesnt look too bad, just wish it had some other choices for microstepping.

Hi!
looks like a good stepper driver, just wondering how it will work with Windows.
You mentioned that it is important to "make sure your PC/OS can handle the fast pulse train" is this Lynux hardware?

Also do you know how to make one from scratch open source?

Thanks!
